SHADE FOR INCANDESCENT ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent No. 479,207, dated July 19, 1892. Application led February 29, 1892. Serial No. 423,234. (No model.)

To aZZ whom, may concern,.-

Be it known that we, WILLIAM J. EDMoND and THOMAS J. KEON, citizens of the United States, and residents of Philadelphia, Pennsylvania, haveinvented certain Improvements in Shades for Incandescent Electric Lamps, of which the following is a specification.

The object of our invention is to provide a combined shade and reflector for incandescent electric lamps or other lights, the device comprising a series of petal-like sections which may be folded partially or wholly together to soften or wholly exclude the light of the lamp, as more fully described hereinafter.

In the accompanying drawings, Figure l is an elevation of our improved shade applied to an incandescent electric lamp, the sections of the shade being folded together to wholly exclude the rays of light. Fig. 2 is a similar view showing the sections partly opened. Fig. 3 is a similar view showing the sections wholly opened. Fig. 4 is a sectional plan View on the line 1 2, Fig. 2, on a somewhat larger scale. Fig. 5 is a perspective view showing one of the sections detached from the shade. Fig. 6 is a transverse section on the line 3 4, Fig. l, on an enlarged scale, showing but two of the sections. Fig. 7 is a per spective view of the detachable collar by which the shade may be applied to the socket of an ordinary incandescent electric lamp, and Fig. 8 is a view of a modification.

Our invention is principally intended for application to the sockets of incandescent lamps of ordinary construction, the attachingcollar A (shown in Fig. 7) being made of suitable shape to accommodate the socket for which it is intended and being clamped in position thereon by means of a screw a, passing through ears l), projecting from the opposite end of the split ring c, which forms the upper portion of the collar. This split ring supports a lower ring (Z, to which it is attached by a series of connecting-strips e, and the ring dis provided with one or more catches for the support of the shade, the simplest form of catch being illustrated in Fig. 7 and comprising tongues f, stamped out of the ring d, which is made of suitable material to give the tongues f a slight spring. If desired, however, the catches may be attached to the collar CZ in any other suitable manner.

Surrounding the collarA is a ring or collar B, held in position by the catches f, which pass through openings g in the ring B in such manner that the ring B may be readily removed by pressing on the catches f and forcing them out of engagement with the openings g. This ring B forms the base of the shade, and its lower end is provided with an internal iiange 7L, in which is an annular groove 7,', extending through the body of the ring B, and through the ring and its flange is cut at regular intervals a series of notches j,in which are placed the upper ends or pivot-blocks of the petal-like sections C, each of the pivoting-blocks, as shown more clearly in Fig. 5, beingin the form ot' ablock 7c, having projecting tongues Z Z and having an orifice fm, through which the pivot-pin n passes. If desired, the pivot-pins n may be separate from each other and the opposite ends of the pins be carried by the iiange h; but We prefer to make the pivot point or pin in the form of a ring which encircles the ring B and is adapted to tit within the annular groove 'L'.

' The shade is composed of anumber of sections C, each in the form of apetal, and arranged in such a manner that their edges will overlap to a greater or less extent, depending upon the extent to which the shade is opened, and each petal is suitably curved to the shape of the globe of the lamp, so that when wholly closed they will entirely cover all portions thereof.

Surrounding the rin gB is an operating-ring D, through the body of which passes a pin p, preferably carrying an anti-friction roller q, adapted to a cam-slot o" in the ring B, so that as the ring D is turned the traversing of the cam fr by the anti-friction roller g will eect the vertical movement of the ring D, and to facilitate movement of this ring it is preferably provided with an exterior ring s, having a serrated or roughened periphery, as shown in Figs. l, 2, and 3. The lower end of the ring D flares outwardly, forming a groove t, and is provided with a flange u, substantially circular in cross-section, and adapted to it between the tongues Z and the tongues Z of ICO petal-like sections may be opened to anydesired extent, and when opened will remain in any position to Which they may have been moved. Beneath the flange u is a ring w to protect the tongues Z'. The overlapping of the sections is such that even when the shade is fully opened, as shown in Fig. 3, the-escape of light in a horizontal plane between the1 sections is prevented, and when the under` surface of the sections are polished or provided with reflecting-surfaces the light ymay1 be concentrated as much as desired.

In Fig. 8 is illustrated a modification, in

which the rin(r B is rovided With a nuove n p b ra',vvith which a single tongue Pin the ypetals engages. It is preferred to makethe petals of sheet metal, which may be stamped in the proper form; but anymaterial may of course be used-such, for instance, .as paper, vulcanized Iiber,`celluloid, glass, or textile materials, if preferred.

Having thus described our invention, We

claim anddesire to secure by Letters Patentl. A shade comprising a series of sections pivoted to a base, a tongue or tongues `projecting from each of said sections, a grooved operating-ring engaging with said tongue, and means for eiecting the vertical movement of such grooved ring, substantially as specified.

2. A shade comprising a base-ring, a series of sectionstpivoted thereto, tongues projecting from said sections, a grooved operatingring encircling said base-ring and adapted to engage 'with saidtongues, and means for effecting the vertical movement of said grooved operating-ring, substantially as specified.

A shade comprising a base-ring, a series of sect-ions pivoted thereto, tongues Z l on each of said sections, an operating-ring, a flange thereon adapted to fit between said tongues, and means for effecting the vertical movement of said operating-ring, substantially as specified.

4. A shade comprising a base-ring, an intei-nal flange h thereon, and having a peripheral groove vl, a series of sections, pivot-blocks thereon, a pivot pin or ring passing through each of said blocks and adapted to said groove i, tongues projecting from said pivot-blocks, anda grooved operating-ring, to which said tongues are adapted, with means for eiecting the vertical movement of said ring, substantially as specified.

5. A shade comprising a base-ring, an internal iiange thereon, and having a peripheral groove fi, a series of overlapping sections, pivot-blocks thereon, a pivotpin or ring passing through each of said blocks and adapted to said groove i, tongues Z l', projecting from each ot said sections, an operating-ring, a flange thereon adapted to t between said tongues, and means for eectin g the vertical `movement ot' said operating-ring, substantially as specified.

6. A shade comprising a base-ring, an internal ange thereon, and having a peripheral groove i, a series of overlaippin g sections, pivot-blocks thereon, a pivot pin or ring passing through each of said blocks and adapted to said groove e', tongues Z l', projecting from each of said blocks, an operating ring, a ange thereon adapted to it between said tongues, and a pin projecting from said operating-ring and adapted to a cam-groove in the base-ring, substantially as specified.

7. A shade comprising a base-ring B, having an inclined cam-groove r, a series of overlapping shade-sections `pivoted to said basering, tongues projecting from each of said sections, a grooved operating-ring engaging with said tongue, and a pin carried by said grooved operating-ring and adapted to the cam-groove of the base-ring B, substantially as specified.

8. A shade comprising a series of sections, each of said sections having one of its edges so arranged as to overlap the edge of thenext adjoining section and its opposite edge being overlapped by another of said sections, substantially as specified.

9. The combination of the base-ring, a series of overlapping sections pivoted thereto, means for operating said sections, and a holding-ring. comprising an upper clamp-ring c and a lower ring d, and catches carried by said lower `ring and adapted to engage with said base-ring, substantially as specified.

1 0. |The combination of the base-ring, the shade carried thereby, openings in said ring, a holding-ring A, secured to the lamp-socket, and tongues f, projecting from said holdingring and adapted to engage with the openngs in the base-ring, substantially as specill. The combination of the base-ring B, having openings, the shade carried bysaid base-ring, the holding-ring A, comprising an upper split ring c, a clamping-screw for holding said ring in position on the socket, and catches carried by said holding ring and adapted to engage with the openings in the base-ring, substantially as specified.

In testimony whereof we have signed our names to this specication in the presence ot' two subscribing Witnesses.
